macOS Big Sur removes the “Power Saving” section of System Preferences, replacing it with a new “Battery” section that extends Mac’s battery reporting capabilities.
A new Usage History feature provides details on the battery life of the Mac over the past 24 hours or the last 10 days, broken down into Battery Level and Display in Use so you can see how your battery is working .
There doesn’t seem to be a detailed rundown on which apps used the battery the most like on iOS, but it does provide a better insight into how the battery drains over time.
Along with the Usage History section, there are Battery and Power Adapter sections that replace functionality that was previously available through Energy Saver. You can choose when to turn off the screen, enable or disable power nap, and more, with split settings for battery usage and usage when connected to power. The programming function is also present.
In the menu bar, clicking on the battery icon now gives you an estimate of the remaining battery life, a feature that was removed from macOS Sierra in 2016. At the time, Apple said the indicator for battery life on macOS Sierra was incorrect and causing confusion. about battery performance.
The battery icon in the menu bar also displays high-energy-consuming apps, such as in macOS Catalina, and offers an option to open Battery Preferences. However, there doesn’t seem to be an option to display the current percentage of battery life in the menu bar.
OSmacOS Big Sur is limited to developers right now, but Apple plans to make a public beta available this July before the software sees a full release in the fall.
